    I got a Growcraft X3 – 330 Watt DIY LED Grow Light Kit. It was fairly easy to assemble even though I’d had no prior experience with electronic wiring. The how-to video and the instructions were a bit confusing at times, though. Other than that, my plants are thriving under this light, and I couldn’t be happier.

    Bought the 330 watt 3 bar. Super Simple to Assemble. Use Ig it in A 4/4 tent. Amazing the Fast Healthy Growth. Using only 330 watts. Definitely buying more. Use one on side walls.

    ChilLED is simply the best buying experience of my entire grow setup. I purchased a X3 and a DIY X4. The wait time said 45 days but they were shipped in 25 days. I was like a kid on Christmas waiting. I contacted customer service about the time frame of shipping and everytime they answered right away. Once my light got here they were easy to setup with the video installation tutorial. I can express enough how happy I am. I know that I will be a long term customer. Thank you

    Set up is easy enough and the light is powerful. Feels a bit barebones due to the functional but janky dimmer switch. Honestly not a big deal imo because I was looking for a good value and these are high quality lights. Be aware however that the DIY lights don’t come with any warranty which makes me a bit uneasy. This is my second purchase so definitely satisfied.

    I bought this light after seeing Vitaly‘s personal story and attention to details for growing indoors with LEDs. I want to support that kind of initiative. The light is great and so far producing good results for tomatoes

    Putting this light together was a breeze. Make sure you follow the typed out instructions as they have the updated wire color connections, the videos do not. This light is a beast and its currently kicking ass in my 2×4 tent. Temps stay in comfortable range and and my super special “tomatoes” love it! Thanks Chilledtech!

    I ordered two of these lights when they were being released. This, I want to add, was at the beginning of the Covid19 shutdown. So, these guys were making these in their warehouse, while all of that was going on.
    Great Job!!!
    To anyone who does not know, ChilLED is made here in the USA! The product, like always, is superior to anything else out on the market. I love my new lights. Big thank you to the ChilLED team that could not have been an easy time. -NiceR

    I was previously using lights from HLG. I’m loving the chilled grow lights a lot more. My plants have begun flowering and look amazing. Setup was easy. I found the instructional pdf to be more helpful than the video.

    I built my X3 light yesterday. It took me a couple hours, because the how-to videos were a bit confusing to me. I wish it had more detailed instructions (also wish the music in the background wasn’t there, as it is annoying and distracting). For example, I wish you guys explained how to use the wago connectors. I also wish you guys were more clear in explaining how to line up the boards so that the + and – are the on the same ends. I know I’m not the only one who screwed it onto the frame and has to unscrew it to turn one of the boards around. The light is incredible, but the instructional video on how to build it was disappointing, and felt rushed and not really well made. Once I figured out the steps to build it, it was actually very simple. The design is extremely well thought out and I respect that. Everything has a purpose, and it has many little details that make it worth its price. It is beautiful, once fully put together. As an artist myself, I am happy to have this light in my house because it really is as beautiful as it is functional/practical.

    This kit was super easy and very fun to assemble. Everything was manufactured perfect.
    I currently have a beefsteak tomato and Boston cucumber under this light. I had them under a t5 light and they did alright but once I put them under this led light, they literally doubled in size in a couple of weeks.
    I am going to buy another one for sure to fit in my 5×5 tent.
